Description

Technical field

[0001] The present invention relates to the field of adult articles, in particular a massage stick structure with airflow-induced flexible tapping motion. State of the art

[0002] Existing adult vibrators generally use a combination of an air pump and a solenoid valve to switch between positive and negative air pressure, thereby simulating a sucking motion or movement at a predetermined frequency similar to the human body. However, practical experience has shown that interruptions or jamming frequently occur during the switching intervals between positive and negative pressure, negatively impacting the user experience. The operating process is not sufficiently linear; prolonged jamming or interruption can easily lead to the flexible vibrator cup becoming detached by sticking and then detaching.

[0003] One existing solution to this problem is generally to use a higher-pressure air pump to prevent the flexible knock cup from detaching during periods of inactivity. However, this also results in a greater air intake force, which does not achieve a better simulation of the human body. Content of the present invention

[0004] The main object of the present invention is to provide a massage rod structure with an airflow-induced flexible tapping motion, which aims to improve the existing drive structure of the flexible tapping cup. A linearly driven air pump is used, so that switching between positive and negative air pressure can be achieved without the need for additional structures such as a solenoid valve, and without any jamming problem occurring during the switching intervals.

[0005] To achieve the aforementioned purpose, the present invention proposes a massage stick structure with airflow-induced flexible tapping motion, comprising: a rigid housing, wherein the rigid housing has an interior, wherein a distribution pipe is provided at the upper section of the rigid housing, wherein the rigid housing has at least one recess, wherein the recess has a distribution opening, and wherein the distribution pipe is connected to the distribution opening; a flexible shell, wherein the flexible shell encloses an outer circumferential wall of the rigid housing, the flexible shell covering the recess and forming an elastic section, and wherein a distribution chamber is defined between the elastic section and the rigid housing; a drive device, wherein the drive device is arranged in the rigid housing, the rigid housing comprising a lithium battery, a printed circuit board (PCB) connected to the lithium battery and a control device connected to the printed circuit board, wherein the drive device is connected to the printed circuit board, and wherein the control device is provided to control an operating state of the drive device; wherein the drive device comprises a rotary device, a telescopic seat, a drive seat, a guide seat and a sealing seat; wherein the rotating device has a drive shaft, wherein the rotating device has an upwardly extending positioning housing, wherein the positioning housing is fixed to the rigid housing, wherein the positioning housing extends upwards from a wall surface of the rotating device, wherein the positioning housing is arranged on an outer wall of the rotating device, and wherein the positioning housing together with an upper wall of the rotating device defines a positioning chamber; wherein the guide seat is fixedly mounted between the positioning housing and the rotation device, wherein the guide seat has an interior space, wherein the drive seat is arranged in the interior space, and wherein the guide seat has a guide groove formed along its height; wherein the telescopic seat has a lower chamber, wherein the guide seat is arranged in the lower chamber, wherein the telescopic seat has a pivotally arranged pivot pin in the lower chamber, wherein an end section of the pivot pin is engaged in the arcuate groove after passing through the guide groove, and wherein an upper chamber is further provided on an upper wall of the telescopic seat; wherein the sealing seat is fixedly arranged at a rear end position of the distributor pipe and establishes a connection between the distributor chamber and a sealing chamber; wherein, when the rotating device rotates, the arc-shaped groove causes the pivot pin to slide along the vertical direction of the guide groove, which vertically shifts the telescopic seat between a position close to the sealing seat and a position away from the sealing seat, and thereby switching the air pressure between the upper chamber and the sealing chamber between compression and relief, and setting a gas pressure in the distribution chamber, and wherein, when the gas pressure changes, the elastic section can deform between an expanded position and a contracted position.

[0006] In practical terms, the following applies: 1. In its practical embodiment, the massage wand comprises a rigid housing and a flexible sheath enclosing the rigid housing, so that the massage wand is preferably rod-shaped (for example, as an elongated cylindrical structure, an elliptical cylindrical structure, or a spherical structure). The massage wand can be inserted into the vagina or positioned at the vaginal opening. During use, the drive device can control changes in the air pressure of a closed chamber to exert a predetermined stimulation on the vaginal wall; the stimulation can be an elastic tactile sensation of the elastic section on the skin or a tactile sensation of negative pressure adsorption (this can be understood as flexible tapping) to stimulate sensitive points in different positions and produce different sensations.At the same time, a haptic sensation of penis dilation simulated by the massage wand can be experienced. 2. The structure comprises a positioning housing, a drive unit (rotating device, drive seat, guide seat, and telescopic seat), and a piston unit (upper chamber of the telescopic seat and sealing seat). The positioning housing acts as a support, allowing the drive unit and piston unit to be designed as a modular structure, thus facilitating installation, production, and assembly. Simultaneously, stability is improved and the volume is reduced, making it easier to integrate this structure into adult products. Through the interaction of the guide groove and the arc-shaped groove, a rotary stroke is converted into a vertical stroke, causing the vertical movement of the upper chamber. This movement switches the air pressure between the sealing chamber and the upper chamber between a compression position and a relief position, thereby achieving a switch between positive and negative air pressure.Furthermore, the switching process is more linear, allowing for more linear control of structures such as a flexible tapping cup, thereby improving the flexible tapping process for simulating the human body, reducing the jamming problem, and improving the user experience. 3. The improved air pump (i.e., the drive unit) allows the control device to regulate the rotational motor's speed, thereby simulating different states. For example, the higher the speed, the higher the frequency of expansion and contraction; at a lower speed, a softer tactile sensation can be provided. Simultaneously, a higher speed can also simulate a larger size, with a more linear transition and greater durability of the drive unit. Naturally, customer-specific state selection control can also be implemented to meet diverse intelligent control requirements.

[0010] As in Fig. 1 to Fig. Figure 11 shows a massage rod structure with airflow-induced flexible tapping motion: a rigid housing, wherein the rigid housing has an interior, wherein a distribution pipe is provided at the upper section of the rigid housing, wherein the rigid housing has at least one recess, wherein the recess has a distribution opening, and wherein the distribution pipe is connected to the distribution opening; a flexible shell, wherein the flexible shell encloses an outer circumferential wall of the rigid housing, the flexible shell covering the recess and forming an elastic section, and wherein a distribution chamber is defined between the elastic section and the rigid housing; a drive device, wherein the drive device is arranged in the rigid housing, the rigid housing comprising a lithium battery, a printed circuit board (PCB) connected to the lithium battery and a control device connected to the printed circuit board, wherein the drive device is connected to the printed circuit board, and wherein the control device is provided to control an operating state of the drive device; wherein the drive device comprises a rotary device, a telescopic seat, a drive seat, a guide seat and a sealing seat; wherein the rotating device has a drive shaft, wherein the rotating device has an upwardly extending positioning housing, wherein the positioning housing is fixed to the rigid housing, wherein the positioning housing extends upwards from a wall surface of the rotating device, wherein the positioning housing is arranged on an outer wall of the rotating device, and wherein the positioning housing together with an upper wall of the rotating device defines a positioning chamber; wherein the guide seat is fixedly mounted between the positioning housing and the rotation device, wherein the guide seat has an interior space, wherein the drive seat is arranged in the interior space, and wherein the guide seat has a guide groove formed along its height; wherein the telescopic seat has a lower chamber, wherein the guide seat is arranged in the lower chamber, wherein the telescopic seat has a pivotally arranged pivot pin in the lower chamber, wherein an end section of the pivot pin is engaged in the arcuate groove after passing through the guide groove, and wherein an upper chamber is further provided on an upper wall of the telescopic seat; wherein the sealing seat is fixedly arranged at a rear end position of the distributor pipe and establishes a connection between the distributor chamber and a sealing chamber; wherein, when the rotating device rotates, the arc-shaped groove causes the pivot pin to slide along the vertical direction of the guide groove, which vertically shifts the telescopic seat between a position close to the sealing seat and a position away from the sealing seat, and thereby switching the air pressure between the upper chamber and the sealing chamber between compression and relief, and setting a gas pressure in the distribution chamber, and wherein, when the gas pressure changes, the elastic section can deform between an expanded position and a contracted position.

[0011] In its practical implementation, this structure comprises a positioning housing 2, a drive unit (rotating device 1, drive seat 3, guide seat 4, and telescopic seat 5), and a piston unit (upper chamber 51 of the telescopic seat 5 and sealing seat 6). The positioning housing 2 acts as a carrier, allowing the drive unit and piston unit to be designed as a modular structure, thus simplifying installation, production, and assembly; at the same time, stability is improved and the volume is reduced, making it easier to install this structure in an adult product.Through the interaction of the guide groove 41 and the arc-shaped groove, the rotary stroke is converted into a vertical stroke, causing the vertical movement of the upper chamber 51. This switches the air pressure between the sealing chamber 60 and the upper chamber 51 between a compression position and a relief position, thus achieving a switch between positive and negative air pressure. Furthermore, the switching process is more linear, allowing for more linear control of structures such as a flexible tapping cup. This improves the flexible tapping process for simulating the human body, reduces jamming problems, and enhances the user experience.
